Overview of this book

This latest edition of the bestselling Packt series will give you a solid foundation to start building projects using modern C# and .NET with confidence. You'll learn about object-oriented programming; writing, testing, and debugging functions; and implementing interfaces. You'll take on .NET APIs for managing and querying data, working with the fi lesystem, and serialization. As you progress, you'll explore examples of cross-platform projects you can build and deploy, such as websites and services using ASP.NET Core. This latest edition integrates .NET 8 enhancements into its examples: type aliasing and primary constructors for concise and expressive code. You'll handle errors robustly through the new built-in guard clauses and explore a simplified implementation of caching in ASP.NET Core 8. If that's not enough, you'll also see how native ahead-of-time (AOT) compiler publish lets web services reduce memory use and run faster. You'll work with the seamless new HTTP editor in Visual Studio 2022 to enhance the testing and debugging process. You'll even get introduced to Blazor Full Stack with its new unified hosting model for unparalleled web development flexibility.

Working with methods and tuples

Methods are members of a type that execute a block of statements. They are functions that belong to a type.

Returning values from methods

Methods can return a single value or nothing:

  • A method that performs some actions but does not return a value indicates this with the void type before the name of the method.
  • A method that performs some actions and returns a value indicates this with the type of the return value before the name of the method.

For example, in the next task, you will create two methods:

  • WriteToConsole: This will perform an action (writing some text to the console), but it will return nothing from the method, indicated by the void keyword.
  • GetOrigin: This will return a text value, indicated by the string keyword.

Let’s write the code:

  1. In Person.cs, add statements to define the two methods that I described earlier, as shown in the following code:
    #region...
